Emacs Theme Manager
Here is an emacs lisp file that I whipped up to help me select a color theme.
I tried some of the suggestions at emacswiki but Do Re Mi would not load on xemacs. The other suggestions just scrolled forward and did not save the state.
To use the theme-manager load the file and bind the keys, that you want to use for moving to the next and previous theme, to the functions
theme-prev. The last theme you stop on is the one emacs will load the next time it starts.
